My sailboat has a Garmin 431 GPS which only converses in NMEA 0183 it also has a Tacktick Micronet 30 speed depth wind system. I want to know if the DMK box will work with these instruments please? I would use a non GPS Ipad to receive data with IRegatta Pro.
Next question, if your box will broadcast wifi on board would I get a box with a GPS or not? I sail on the Great lakes on Ontario.

    Hello Chuck,

    Our DMK 11A has two inputs for NMEA 0183 so in your case it could wire to Garmin GPS and Tacktick instruments and send both streams to iRegatta Pro. For this installation your Tacktic system must have a NMEA Interface box. In this scenario you would not need our GPS box as the location data would be driven by the Garmin.

    Thanks Kevin,
    I believe the the one without the GPS is DMK11 correct? No A.
    Do you guys sell the NMEA interface box?
    Can you tell me pricing and how I place an order and manage shipping? I live in Ontario Canada.

    Yes the DMK 11A is the one without the GPS. We do not sell the Tacktic interface box but Defender Industries sells it online at:


    To order our box for shipping to Ontario I would suggest the Paypal tab on our website. If you use that order we will ship you one direct.

    Hi Kevin,
    I just looked on the my Hobie 33, it appears I have a Tacktick T127 wireless box. Since it is transmitting wirelessly now will that work with DMK 11 A or do I still need a T122?
